There are several failures of buildings and bridges and other constructed facilities; it is important to learn from these failures so that such catastrophes do not occur in the future (Feld and Carper, 1996, Levy and Salvadori, 2002, Raikar, 1987, and Salvadori, 1990). Failure of buildings due to construction of a deep trench in the adjoining plot is not a new phenomenon, although it is undesirable.

Similar fatal collapses have occurred in various other parts of India and across the world.
